UK Anti-Doping (Ukad) has announced that British world heavyweight champion Tyson Fury is to face a charge over the presence of a banned substance.
Ukad confirmed that Fury was provisionally suspended in June, though that was lifted pending a hearing.
In a statement, a UKAD spokeswoman said: "In response to public comments made by Tyson and Hughie Fury's representatives, UK Anti-Doping can confirm that both boxers were charged on 24 June 2016 with presence of a prohibited substance. Mandatory provisional suspensions were imposed pursuant to article 7.9.1 of the UK Anti-Doping rules.
"The UK Anti-Doping Rules allow athletes to challenge the imposition of a provisional suspension and the independent National Anti-Doping Panel (NADP) today lifted the athletes' suspensions, pending full determination of the charges. These charges will be heard at a hearing before the NADP in due course.
"UK Anti-Doping will not comment further on the case until due legal process has been completed."
On Tuesday, Fury announced he would sue the organisation over allegations he used a performance-enhancing substance.
"The two boxers strenuously deny taking any performance-enhancing drugs," said lawyer Lewis Power.
"However, during the last five weeks, leaks about these charges have appeared in the press and both boxers have been the targets of continual abusive language on Twitter."
